Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cooling air is drawn from the area surrounding the vacuum cleaner, then cooling air supply is simple, but the cooling path becomes long causing heat losses and contamination risks
Solution Approach 1:
The invention extracts the cooling air intake function from the external environment and relocates it to the interior of the housing. By creating an internal cooling air circulation system, the patent eliminates the need for long external supply ducts while maintaining effective cooling, thus resolving the contradiction between manufacturing simplicity and cooling efficiency.
Solution Approach 2:
The patent introduces an intermediary structure - the cooling air duct system within the housing - that mediates between the cooling components and the ambient air. This internal duct system serves as an intermediate cooling air source, reducing the path length and preventing contamination while maintaining the cooling function.
2Ease of manufacture
If cooling air is drawn from the area surrounding the vacuum cleaner, then cooling air supply is simple, but dust or dirt can enter the interior of the vacuum cleaner
Solution Approach 1:
The invention extracts the cooling air intake function from the external environment and relocates it to the interior of the housing. By creating an internal cooling air circulation system, the patent eliminates the need for long external supply ducts while maintaining effective cooling, thus resolving the contradiction between manufacturing simplicity and cooling efficiency.
Solution Approach 2:
The patent creates a controlled internal environment within the housing that serves as a relatively clean atmosphere for cooling air intake. By utilizing the interior space as the cooling air source, the system avoids direct exposure to contaminated external air, thereby reducing dust and dirt entry risks.
3Volume of moving object
If components are located within the vacuum cleaner housing, then the vacuum cleaner structure is compact, but components are poorly reached by cooling air
Solution Approach 1:
The patent segments the housing interior into different zones, creating dedicated cooling channels and pathways that deliver cooling air directly to components located within the compact housing. This segmentation allows effective cooling distribution throughout the compact structure without compromising component accessibility to cooling air.
Solution Approach 2:
The patent utilizes three-dimensional space within the housing by creating vertical and horizontal cooling channels, and by orienting components at different angles and positions. This dimensional approach ensures that cooling air reaches all components effectively within the compact housing volume.

AI summary
The present invention relates to a suction device with a channel for supplying cooling air to at least one component of the suction device, wherein the at least one component of the suction device is arranged within a housing of the suction device. The channel is designed such that cooling air is drawn in from an interior space of the housing of the suction device and passed by the at least one component of the suction device. This allows for a cooling channel with a particularly short loss path, through which the cooling air can be passed by the at least one component of the suction device with minimal loss of cooling capacity. In this way, particularly effective cooling of the at least one component of the suction device can be achieved. In a second aspect, the invention relates to a method for operating such a suction device, which enables optimal cooling of the at least one component of the suction device.
